Statement
Reference
Animals expressing park[Scer\UAS.T:Hsap\MYC] under the control of Scer\GAL4[Mef2.PR] results in mitochondria of almost normal size in the adult thorax.
Expression of parkScer\UAS.T:Hsap\MYC in the notum of wing imaginal discs (under the regulation of Scer\GAL4ap-md544) induces a marked cleft in the thorax, in a park-dose-dependent manner.

Reference
Co-expression of Pink1[Scer\UAS.T:Ivir\HA1] and park[Scer\UAS.T:Hsap\MYC] under the control of Scer\GAL4[hs.PB] at 25[o]C results in pupal lethality, but at 18[o]C, several adult escapers are obtained. These escapers have smaller mitochondria in the indirect flight muscles compared to controls. Co-expression of park[Scer\UAS.T:Hsap\MYC] in adults expressing opa1-like[Scer\UAS.T:Zzzz\FLAG] under the control of Scer\GAL4[Mef2.PR] results in smaller than normal mitochondria in the adult thorax. The swollen mitochondria phenotype seen in dopaminergic neurons of Pink1[B9] mutants is suppressed by expression of park[Scer\UAS.T:Hsap\MYC] under the control of Scer\GAL4[ple.PF].
Expression of park[Scer\UAS.T:Hsap\MYC] under the control of Scer\GAL4[hs.PB] partially suppresses the mitochondrial swelling phenotype in Pink1[B9], park[1] double mutants.
Expression of parkScer\UAS.T:Hsap\MYC under the control of Scer\GAL4hs.PB markedly suppresses the downturned wing and crushed thorax phenotypes seen in Pink1B9 flies. The indirect flight muscle defects are also suppressed in these animals. The loss of dopaminergic neurons in the adult brain and the enlarged mitochondria phenotype seen in the remaining dopaminergic neurons is also significantly suppressed. The rescued flies show increased climbing speed and have some flight ability.
The thoracic cleft formation observed in parkScer\UAS.T:Hsap\MYC overexpression mutants (Scer\GAL4ap-md544) and bskK53R.Scer\UAS mutants is mutually enhanced by their co-expression. The thoracic cleft formation observed in parkScer\UAS.T:Hsap\MYC overexpression mutants (Scer\GAL4ap-md544) is suppressed by co-expression of bskScer\UAS.cBa. Overexpression of pucScer\UAS.cMa and parkScer\UAS.T:Hsap\MYC in the notum of the wing imaginal discs, under the regulation of Scer\GAL4ap-md544 enhances the thoracic cleft observed in each single overexpression. Expression of parkScer\UAS.T:Hsap\MYC in the notum of the wing imaginal discs, under the regulation of Scer\GAL4ap-md544, in hep1/+ mutants enhances the thoracic cleft phenotype observed in parkScer\UAS.T:Hsap\MYC/Scer\GAL4ap-md544 mutants alone. Co-expression of hepAct.Scer\UAS, with parkScer\UAS.T:Hsap\MYC, in the notum of the wing imaginal discs, under the regulation of Scer\GAL4ap-md544 suppresses the parkScer\UAS.T:Hsap\MYC phenotype of thoracic cleft formation resulting from abnormalities in JNK signalling during thorax closure. The thoracic cleft formation observed in parkScer\UAS.T:Hsap\MYC overexpression mutants (Scer\GAL4ap-md544) is suppressed by co-expression of Traf1EP578. Overexpression of pucScer\UAS.cMa and parkScer\UAS.T:Hsap\MYC in the notum of wing imaginal discs, under the regulation of Scer\GAL4ap-md544 enhances the thoracic cleft observed in each single overexpression. Overexpression of Pk92BScer\UAS.T:Zzzz\FLAG and parkScer\UAS.T:Hsap\MYC in the notum of wing imaginal discs, under the regulation of Scer\GAL4ap-md544 partially suppresses the thoracic cleft observed in parkScer\UAS.T:Hsap\MYC mutants. The thoracic cleft formation observed in parkScer\UAS.T:Hsap\MYC overexpression mutants (Scer\GAL4ap-md544) is enhanced by co-expression of Pk92BK618M.Scer\UAS.
Co-expression of Traf2EP1516, with parkScer\UAS.T:Hsap\MYC, in the notum of the wing imaginal discs, under the regulation of Scer\GAL4ap-md544 suppresses the parkScer\UAS.T:Hsap\MYC phenotype of thoracic cleft formation resulting from abnormalities in JNK signalling during thorax closure.

Comments
The mitochondrial morphology in the indirect flight muscle of park[1] mutants is fully rescued by expression of park[Scer\UAS.T:Hsap\MYC] under the control of Scer\GAL4[hs.PB]
The park1 dorsomedial dopaminergic neuron morphology and loss phenotype can be completely rescued by the expression of parkScer\UAS.T:Hsap\MYC under the control of Scer\GAL4Ddc.PL.
